Answer:
1 hour and 30 minutes.
Step-by-step explanation:
While carrying her fancy 360-degree camera, a crew artist Sarah Jane can walk at a rate of 2 miles per hour.
We are asked to determine the time required by Sarah to walk to a place that is 3 miles away from her.
Since Sarah can walk at a rate of 2 miles per hour.
Hence, she walks 3 miles in hours i.e. 1 hour and 30 minutes. (Answer)
{Here we have used the unitary method assuming that Sarah walks at a constant rate}
